Reviews the project to build an 8 mile tunnel, internal diameter 7.Sft, as part of an a~aeduct system in Utah, UsA. Problems are relocated in connection with binding of the tunnelling machine in a large fault zone, ";ith convergence and with sealant failure in the segmented lining Joints. These led to a halt in construction during 19~9: plans for completion are discussed. 811117 ELASTIC SOLUTIONS FOR A DEEP CIRCULAR &"I.J'N~'~__..., TECHNTC~L NOTE Pander, M J Geotechnique, VS0, N~, June 1980, P216-222 Discusses 3 cases: (i) stresses applied at a distant bound~z-~, (2) tt~uel excavated in a prestressed medittm, (3) interaction between a tunnel excavated in a prestressed medium and a tunnel lining. 811118 S O ~ PRACTICAL ASPECTS OF CONC~I~JAL MODELS IN TUg~I N~ Muir Wood, A M Proc hth Congress International Society f~r Rock Mechanics, Montreux, 2-8 Sept 1979, Vol 3, P~7~-278. ~ b l Rotterdam, A A Balk~ma,
